Churn



PATENT rrrcn.

CHARLES A. LORENZ, OF RIMERTON, PENNSYLVANIA.

CHUR-N.

SPECIFICATION forming part of Letters Patent No. 339,308, dated April 6, 1886.

Application filed October 29, 1885.

To all whom it may concern,.-

Beit known that I, CHARLES A. LORENZ, -a citizen of the United States, residing at Rimerton in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to improvements in that class of ehurns known as vertical double-dashcr churnsf and it consists in the peculiar construction, novel arrangement, and combination of devices, as will be hereinafter more fully set forth, and particularly pointed out in the appended claims.

In thc accompanying drawings, Figure l is a perspective view with the body or tub partly broken away to show the position of the dashers, and Fig. 2 is a view of one of the dashers removed.7

Referring to the said drawings by letter, A indicates the body ofthe churn for holding the cream, and may be of tub or other suitable form. This body is provided with a removable top composed of two sections. (Indicated by the letters B and C.) The section B of the cover is ol' a greater diameter than the section C, and is provided with two vertical apertures, o a, to receive the dashcr-stems, and a vertical frame to support their operating mechanism. rIhis frame is composed of two pairs oi' vertical parallel standards, D, which are connected at their upper ends by a transverse horizontal strip, b, which serves to hold the same at the proper distance apart.

E indicates transverse strips, which are secured at opposite ends to the parallel uprights or standards and furnish a bearing for the axle of the main driving-gear F, which rotates between the said standards. Engaging with this gear F andv journaled in the standards D are two small gears or pinions, d, the fixed axles oi' which are extended and provided at their ends with crank-arms c. These crankarms are connected at their outer ends with the upper ends of the dasher-rods by means o1' Serial No. 181,259, (No model.)

pins, as shown. lVithin the tub at dialnet rically opposite points are vertical guidestrips G G, which serve to guide and prevent interference ofthe dashers in their movements.

H indicates the dashers, which are composed of two similar approximately are shaped strips, I I, the inturned ends of which are provided with plain bearing portions g g, which are designed to engage the opposite sides of the guide-strips G during operation. The under-sides of these strips I are provided at suitable intervals with transverse recesses, as shown, which recesses may be of dovetal form, and the blades L are seated in these recesses.

In operation it will be seen that when the dashers are arranged in the churn the blades of one dasher will extend inward beyond the ends ofthe blades of the opposite dasher, thus covering nearly the entire bottom of the churn, and serve in breaking up the globules and churning the cream.

I am aware that it is not new to provide a churn-body with internal opposite dasherguides, and that dashers having arms which cross each other have heretofore been used. I am also aware that similar gearing has been used for driving the dashers and arranged upon a movable cover, and therefore do not claim such devices broadly.

Having described this invention, what I clairnis- The combination, with the churn-top carrying the operating mechanism, of the dashers, constructed as described, and composed of the approximately arc-shaped strips having inturned opposite ends, and the blades arranged to pass each other, and the body having the diametrically arranged vertical guide-strips to be engaged by the said inturned strips, substantially as specified.

In testimony whereol1 I aiix my signature in presence of two witnesses.

CHARLES A. LORENZ.
